Abstract
A hand-held rebreather/breathing apparatus for high altitude pre-acclimatization and training. Air exhaled by a user is directed to a reservoir bag for cooling and condensate collection. At inhalation negative pressure created a mixing chamber forces the air stored in the reservoir bag to pass via CO2 absorption chamber where it may be mixed with a fresh portion of the ambient air that influxes via orifice(s) communicating with this chamber. Baseline of the minimum oxygen concentration in inspired air can be pre-set by means of adjustment of the maximum volume of the reservoir bag and/or by means of altering of the number or diameter of one or a plurality of orifices for commination of the ambient air. Biofeedback may be provided by an oxygen monitor.
Claims22
An apparatus for breathing an air mixture expired by a user, providing an air mixture which has lower oxygen concentration than the ambient air, said apparatus comprising:
- an expiratory path, said expiratory path communicating with a reservoir, said reservoir being of adjustably variable volume;
- an inspiratory path communicating with said reservoir through a CO2 absorption chamber;
- and
- a directional valve, said directional valve allowing single direction flow of air through both said expiratory path and said inspiratory path;
- and
- means of communication of said expiratory path and said inspiratory path in sealed engagement with the respiratory system of a user.
